Hi Martin,

<offtopic>
At Debris Publishing, Inc. (www.DebrisPublishing.com) we have built Quuve,
a fully extensible investment management platform that deploys on Gemstone.
Authoring is done in the Pharo environment -- please see my inline answers
below for more information. Please also check out our Quuve overview video
[1] to see more. We are actively seeking a strategic partnership with a
firm like UBS — please reach out if you would like to discuss potential
partnership opportunities.

We develop on Pharo and deploy on GemStone. We can even write some GemStone
code in Pharo using the MockGemStone compatibility package.
When we really really need to develop *on* GemStone, we use tODE.

We use Monticello and Metacello. With Metacello we can define different
things to be loaded on different Smalltalks (for the things that are
different).
For extensions we use a separate package. Actually, we have separate
packages for Pharo and from GemStone. We even had separate packages for
different Pharo/GemStone versions.
We also have a separate package for "overrides" which are usually fixes to
either GemStone/Pharo that are about to be fixed soon in future releases
but that for the moment we need it fix it.
Of course, via Metacello  we can then decide which packages are loaded in
which Smalltalk.

Currently we use Monticello, but we want to move soon to git. We will
continue using Metacello regardless.

4)      What mechanism do you use for uploading code to your production

We have either bash scripts (using Topaz) as well as buttons / links to
trigger updates from within the very same running web application.
Obviously this button is properly secured, allowed only for admin users,
etc etc.
Sometimes... depending on the update (for example, upgrading to a new
GemStone release , or a heavy migration script), we must either shutdown
the stone for a while or do a much smarter approach.


If you would like more details, please let me know.
