searching transactions in CiviCRM & Address book integration in 4.6

This is actually a feature request and a question. First the question:

For 4.6, is the option to replace the Address Book with CiviCrm addresses only available in the CVS? The release on the modules page appears to be the Dec 05 version? If so, which if any 4.6 release in CVS is usable in production? Scanning the latest main code, it looks like transactions are now always written to CiviCRM activites as donations? (The else clause to write other transaction types seems to be missing!). Is this correct?

My feature request: I changed my working (1.1.2.3) module code to add a list of SKUs to the Transaction Type field written to the CiviCRM activity log table. This enables searching from CiviCRM for all contact who purchased a particular product by SKU (only the activity type and date range fields are searchable in CiviCRM, the summary field is not searchable). This is really useful for creating a (smart) group for further processing. As the CiviCRM devs have no plans (I asked) to make the summary field searchable, this might be a feature others whould find useful?
