Just out of interest, is _anybody_ active in this thread an expert on
security? I certainly am not, which means that the proposal I'm
currently putting together probably has a whole bunch of
vulnerabilities that I haven't thought of. (Though there's no emphasis
on encryption anywhere, just signing. I'm *hoping* that RSA public key
verification is sufficient, but if it isn't, it would be possible for
a malicious user to make a serious mess of stuff.) But I'm under no
delusions. I don't say "this is secure" - all I'm saying is "this
works in proof-of-concept".
