At this point, no payment is being made to Microsoft for any bit of Scalix software, so if you worry about any of your dollars paid for a commercial Scalix version going to Redmond, I can assure you that that's not the case.
The license agreements we announced for both Active Sync and the OETP protocol have a fee structure associated with it, as is usual for licensing commercial code or protocols.
For ActiveSync, we have also announced that we will launch a product based on the licensed specs. The initial version of this will be available with Scalix 11.4, as an optional, add-on to the commercial versions of the Scalix product, to be licensed from us per wireless user. The licensing cost of this addon includes some fee to Microsoft for the use of their specifications and protocols. For this, you get full assurance of compatibiity with the ActiveSync protocol and compliant devices.
So, as long as you don't buy/license that specific feature from us, there is nothing to be concerned about; if you do, you will actually already have bought into the concept anyway, because you will be using either a Windows Mobile device or a third party device. Third party devices supporting ActiveSync from Palm, Nokia, Sony-Ericsson and soon to be Apple with the 2.0 iPhone will contain software involving Microsoft licenses as well, including fee structures agreed on between Microsoft and those vendors.
If we implement OETP to support Outlook without a connector, the same would apply here. At this point, we haven't finally taken any decision on whether and when we move from the connector to a OETP-based solution and whether such a solution would fully replace the connector or also be offered as an optional alternative. The discussion in this thread is relevant for making those decisions.
Again, I don't see a showstopper impact on community use, because all of this is only relevant for you if you're using Outlook, in which case you're already licensing software from Microsoft anyway.
In any case, we are not planning to make any core part of Scalix dependent on any of those licensed specifications and we are committed to offer free versions of Scalix without any material licensed from Microsoft in the future; this includes our free Community Edition product.
The financial details of all these agreements are all under non-disclosure, so please don't start asking about them!
Best,
Florian.
