We offer support for the ERP implementation. We dont differentiate 'certified', 
non certified, commercial/propreitary etc in our implementations. Its one 
support and just one, whether he has a bug in the purchase module, or another 
community module, we fix it.

Flat price or per hour pricing is just a commercial detail and depends on what 
the customer purchases.

It's the poor coding methodology (Cowboy Coding 
http://en.wikipedia.org/wiki/Cowboy_coding) and process within Open ERP SA that 
make this difficult. Please have a look at this piece of code from tryton sale 
module:

http://hg.tryton.org/1.6/modules/sale/file/0b436b131d56/sale.py#l143

This shows how easily migrations are managed in Tryton because, migrations are 
part of the module's object itself. Easy to maintain, manage and deploy. Tryton 
does not accept contributions which have a schema change and do not provide 
migration scripts along with it.

In my not so humble opinion, OpenERP SA wants to sell the migration scripts, 
and hence dont do the migrations along with the schema changes, and not because 
they really cant do it?

Or, is there something I am really missing here? please correct me if I am 
wrong. I don't understand why you have to make this migration such a complex 
process when the framework already supports it?

I agree, OpenERP SA is not 'big' evil compared to many companies out there, but 
the fact remains - from your own examples of failed opensource projects - they 
are also commercial open source projects like OpenERP.

Also fabien are you publishing the migration scripts along with the other SFD 
modules? (Sorry to repeat if you have explained elsewhere)
