Sure. That would be a very good start. Moreover it would be a big help
for the people who are trying to flee from the command line.
If you have any queries, would be glad to help. :-)
We (cc'd the others) started upon a CI stack having both CI support (The
High level CI also) LGPL'd, so that anyone is free to use that code in
applications. With this library anybody wishing to use it will get the
advantages of all CI types (that was the basic idea) without having
independent application bothering to rewriting the CI stack with
different CI types.
We are still working on this (not yet complete). I have been almost
sleeping.. ;-) due to a broken link from my ISP.
