In this case, sharing may be possible. I can ask anyway.

Can you make a quick list of the additional functionality you would like
I seem to recall "rich sequence format" was one of GCG's major extensions.

Interesting. I see it mentions Pipeline Pilot. EMBOSS is an ISV partner
and committed to interfacing EMBOSS applications as Pipeline Pilot
I hope there is some source code release. We had the source code at
Sanger not just for EGCG - but also because the sequencers needed more
than the 350kb limit on sequence length.
But I see no quick way to decide on possible source code licensing. Too
many authors, too many companies/institutes. I am not surprised that
nothing is promised at this stage.
Hang on to your licences though ... one (legally speaking) relatively
easy possibility would be a cheap source license for existing licensees.

That would be difficult ... and I am not too confident of the status of
SRS5 code anyway. But there are some alternatives around.

Well, there was at least a year when I tried to make all the code
changes needed for 9.0 and worked closely enough with GCG for the EGCG
users to upgrade to version 9.0 (many were using the external users
licence and had no real choice).
The problems were with the code itself. It took a lot of effort to
convert to 9.0, which made it worth the effort to write new libraries
and even rewrite applications for EMBOSS - 3 years for 2 developers to
Source code licensing was a problem too ... I had a special licence that
allowed me to distribute code to other sites who had source code ... but
they would still be unable to send code to me.
Ideally I would have given EGCG to GCG in exchange for the right to
reuse my own code, but that never happened. A pity, as it cost us no
extra effort in the end to reimplement and a lot of GCG users lost out.
Oxford Molecular were as helpful as they could be at the time, but all
the decisions were left to GCG. In those days open source was something
that scared companies, so I was not surprised by the result. Sad though,
as it immediately made EMBOSS into a competitor rather than a partner.
It has taken us 10 years (and some luck) to become an Accelrys partner.

Hah! Not the one I meant (VADMS had an alpha binary release). The beta
test was at HGMP/RFCGR in Hinxton - where the EMBOSS development team
was and it was their closure that threw EMBOSS into crisis mode.
Susan's TOPO was one of our first EMBASSY package add-ons, along with
Will Gilbert's MSE editor.
An early version of MSE was used by GCG for several of their editing
applications, so at least that and GDE 2.3 are currently available with
source code. EMBOSS's MSE is under GPL. I will try to figure out what
GDE's licence really means.
