Since ECCoin is based off Peercoin, it will need the yet-to-be-released changes that will allow p2pool to work with these coins. There is currently a protocol incompatibility.
There will be a change with the release plan of peercoin. I have decided to include a minor protocol change for future p2pool support so the release will become a mandatory upgrade release. There will be at least 4 weeks or more upgrade window provided to users. The previously planned v0.3.1 will become the v0.4.0 release, and the previous v0.4 development would become the v0.5 development.
Peercoin v0.4 is going through final round of validation. Release candidate will be announced in a few days once all tests complete and build starts. The upgrade schedule will be fixed before release candidate according to what I described last week.
Oh well... at least I have my ECC vanity address: ESnowLehcXPQoGFBCgS8ZHzCfHXW3VUk48
