Select on the Iyonix is fundamental to ROD's (ROL's) plans for the future so I don't know where "ROL is trying to wriggle out of doing Select on the Iyonix comes from". They could have worded the posting better. As to why ask on the Select mailing list surely that is the obvious place to start (i.e. existing customers), I expect they will also ask on the Iyonix mailing list.
I do understand those people who are reluctant to use 'beta' software, and releases do need to be managed, but to some extent Castle have been doing that for the last two years and have not attracted criticism!
In view of the complaints (unjustified I believe) about Castle's recent email shot ROD may have been a bit wary!
