A while back, I started working with William Swanson on a script template format to allow for interoperability in accounts between different wallets. We made some progress, but both of us got pretty busy with other projects and general interest was still quite low.
It seems interest has picked up again, especially in light of recent developments (i.e. CLTV, relative CLTV, bidirectional payment channels, lightning), where nongeneralized script formats will not readily support the rapidly advancing state-of-the-art in script design.
Comments, suggestions, and collaboration are welcome.
