Limited uses of /Beam & Warmup/Cooldown

[TomLewis]

Can we set limited uses of /beam?

For example, if you are killed then you cannot use your last /beam (it gets reset).

And to prevent people using a ship as an extra /home to raid or use as a /back, have limited uses (say 1 use) to prevent abuse.

It would also be nice to have warmup/cooldown for the teleport, I can do this with CMI warmups/cooldowns to fit in with all my other warmups, but that's just an alias to a command. any way to work with CMI warmups/cooldowns via a hook?
