It sounds like you've re-invented CTM rather than a CVSup replacement.
Would you care to provide a comparison of portsnap with CTM?  Based on
your description, the differences are:
- portsnap uses HTTP, CTM uses either FTP or mail.
- portsnap is always signed, CTM is only signed via mail.
- CTM is part of the base system
- ports-cur CTM deltas are currently generated every 8 hours
