Would be fine for me, depends on the community, and it is one of those =
chunks that make many stall...

The reason for building on bitcoin/bitcoin directly is that this created =
a history of all changes, and this way I had a working version running =
each day while doing the refactoring - with my wallet at stake!

However, I think perhaps the bitcoin project should be split into a =
library, with a prototype client and the actual clients. This library =
facilitates this.

Cheers,
