I don't think it would be inappropriate to write a ROAM node for SSG.

I agree that it seems like a rather higher level feature than SSG would
normally implement - but it's a feature that would be VERY hard to implement
using only the existing SSG API - and it's popular enough to warrant being
something that SSG should not prohibit.

I havn't played much with ROAM - but the general wisdom seems to be
that implementing the entire algorithm is counter-productive - something
about one of the optimisations that - erm - pessimises.

Anyway - I think it's not a bad idea - but to steal an acronym from the
PPE group:  NIV12.  (Not In Version 1.2)
