Not meaning to disagree with your clearly superior experience but some of the answers require a few qualifiers.
I don't think "all smart weapons" can be mounted on "any aircraft" and used on "any target" as the original post states. Mavericks are fairly versatile that way although they'll struggle to actually hit a fighter jet.
True in the case of the laser spot, however it would be fair to say that the aircraft still needs a datalink so that HUD can provide targeting info and the LGB can be launched within parameters. With radar guided weapons we need to distinguish between SARH and ARH. The latter can be launched without post launch support, however they still need the software interface to inform the pilot of when they are 'locked' and not having datalink support from the launch aircraft will severely limit effective range. Without mid-course update AMRAAMs (at least early ones), were found to be less effective than the older Skyflashs when launched from outside self-lock range if I remember rightly.
True but it does limit effective range if the aircraft can't provide it with an INS reference pre-launch. You could argue that range is limited by the fact the radar can switch off anyway but I believe MWR on the E models solves that problem slightly.
