A few comments on the protocol:
1> It seems overly complicated. If you only allow one MESS and one
PAGE for each send, you shold collapse it into one verb, e.g.
-> PAGE 5551212 Your network is hosed
<- 250 Page Sent
<- 221 Goodbye!
I helped build a pager system with a very similar protocol. Don't
needlessly multiply entities.
2> You should allow for multiple pager IDs per message.
3> Meaningful error responses should be numeric, with arbitrary
ASCII strings appended for human-readability.
4> Some form of authentication should be provided.
That aside, I like your approach,and this is something that sure could
Is this really appropriate for ietf-822?
