Mike -

I appreciate your concerns and directness.

the problem about the LSR model is that it is *simply not friendly* to
free and open source CORBA implementations and it requires alot of
implementation effort by the server writers to provide something.
This puts a high barrier of entry to people using this.

(let me remind you that LSR uses alot of valuetypes, which are
not available in most free orbs and in particular the perl and python
orbs, and the Cos:: definitions, which are both not available in
free orbs and pain to implement oneself. The specification is too
high, too focused on bought-in components and too focused on
enterprise level interoperability to make any sense for academic
code interoperability).

I disagree. It is quite sensible to have internal interfaces which 
represent what is or is not able to do, and why not make them CORBA
IDL interfaces? That is what alot of other projects do (eg, GNOME). 
CORBA does not have to be restricted to an enterprise-only, client
friendly interfaces, but can also be used in internal software for
server friendly IDLs. CORBA can be used for more than the last mile...

I am committed to BSA-LSR, and I want to make it work. When I looked at
providing bioperl as a BSA-LSR style set of interfaces I realised the
best way to do this was to have internal interfaces which I then built
a bridge layer in Java to BSA. *I cannot see any other way of doing this*.
(maybe you can). I see no problem in either sharing that idea of an
internal interface nor encouraging other people to help write the bridge.

If you want to hit the LSR specification directly from bioperl, please
tell me how to do it, because I don't think it is possible.
