Indoor vs. Outdoor sport climbing

This is a pretty broad question; I'll try to answer, but this is going to be long.

You have already noted many differences between indoor and outdoor climbing.

What could you add to this list of safety concerns?

Here are some more ideas on safety:

• You mentioned "pure length of routes"; the issue here seems to be about having a too short rope, so if you don't have a knot on the other end, the climber will fall when he is being lowered (i.e. when both the climber and the belayer least expect that). In indoor climbing, someone more experienced is usually responsible for rope length, so this is less likely to happen.
• Falling rocks are often a major safety concern (you should wear a helmet, even though it doesn't guarantee safety).
• You mentioned insecure bolts, but there may be other hazardous pieces of gear; in the indoor gym they are certainly going to check and replace gear regularly.
• In the case of an accident, help may be far away.

Besides from safety, what are major differences between sport (indoor) climbing and rock (outdoor) climbing?

Differences besides safety (just a few of ideas; there certainly is an enormous number of differences, like between "working out" in a gym vs. running natural trails):

• Most important difference: natural rock is natural; it's just "the real thing" vs. pieces of plastic. Depending on your spiritual inclination, you may absolutely hate climbing gym after you try "real" rock climbing.
• Natural rocks have different types (limestone/sandstone/granite/other), while gyms have plastic, maybe wood and the occasional imitation of limestone (plaster?).
• Holds on natural walls have an infinite number of shapes, so "what you see" is not "what you get" (the hold may be better or worse than you expect). It may also be tricky to find the usable holds, when they are not painted in colours. It's common to have long holdable cracks in nature, which are hard to find in gyms. There is also "slab climbing" (60° walls with almost invisible holds), which you cannot find in gyms.
• Depending on how many natural rocks you have, on-sight climbing may be either very hard or very easy to find. For example, when I go climbing to my usual crag(s), if I want to climb a route I have never tried, it has to be much harder than I am able to (because I have tried almost all routes there already) - but when I go to a new place, I climb just new routes. This is unlike indoor climbing, where they are constantly building new routes.
• Route-finding may be tricky in nature - depends on the site.

Are the difficulties comparable to indoor scaling systems?

Regarding grades:

The idea is to have the grades for indoor and outdoor climbing as equal as possible; however, it's not really possible... For the reasons you mentioned (variable weather conditions; unusual bolting). Here are some more ideas on what differences you can find:

• Some rock-climbing sites have a sort of "snobby" "elitist" culture: they insist that in their site "F6a is hard, and stop complaining", while others say that "F7a should be doable, otherwise no one will come here".
• You may be individually well-suited for a particular type of rock, but ill-suited for another (overhangs/vertical walls).

So a route in outdoor climbing may be easier or harder then an indoor route of the same grade.
