Yeah. LPC is more like Java in the sense that it does run from a form of
VM (perhaps not strictly speaking, but in a theoretical sense). Using the
binary options you can also compile LPC to C at runtime, and keep it
stored as C for efficiency purposes.
The best example of softcode that I know of would be that found on the
Tiny/PennMUSH servers, and another example I could cite is the interpreted
scripting language being built into my mud (the interpretor/executor
written in LPC) to run magical spells.

Yes - basically there are pros and cons to each approach. Putting aside
the hardware usage side (which is perhaps not as important to many people,
at least not until you have a *large* server), the main differences are:
Softcode tends to be easier to learn (citing Tiny/Penn as an example).
Softcode also tends to be harder to do major things in (if it is possible
at all).
Hardcode generally requires a server reboot, and is inaccessible to
players.
And so forth, and so on.
