Afternoon, As requested, I have provided an article[1] on the technical details of creating a much loosing coupling between Teiid Designer and the Teiid client runtime libraries. This enables Designer to support multiple client runtimes in the same session thus connecting to different versions of Teiid at the same time, ie. Teiid 8.2 (JBoss 7) and Teiid 7.7.1 (JBoss 5) so far. If anyone would like further information then feel free to drop me a mail or catch me on irc ...
