I would encourage you to attend the next RDM Plugfest here in the UK.
http://www.plasa.org/rdm/
Both Hamish and I will be in attendance and it is an ideal opportunity to get a great deal of testing done with the latest test tools. For example we will have a very detailed RDM responder test software package being trialled, and several of the RDMLabpacks which will allow you to evaluate the conformance of your Ecco Overled package.
