This is an interesting enough development: the SDK license agreement for Microsoft's Mobile Internet Toolkit (Beta 2) reiterates Microsoft's opposition to open source/Free Software (with the notable exception of the BSD license), claiming that they'll "create, or purport to create, obligations for Microsoft with respect to the Software or (y) grant, or purport to grant, to any third party any rights to or immunities under Microsoft's intellectual property or proprietary rights in the Software. " This includes not being allowed to use open source/Free Software development tools in conjunction with the SDK, according to this EULA.

The license for Microsoft Mobile Internet Toolkit Beta 2 contains the following section:

"(c) Open Source. Recipient's license rights to the Software are conditioned upon Recipient (i) not distributing such Software, in whole or in part, in conjunction with Potentially Viral Software (as defined below); and (ii) not using Potentially Viral Software (e.g. tools) to develop Recipient software which includes the Software, in whole or in part. For purposes of the foregoing, "Potentially Viral Software" means software which is licensed pursuant to terms that: (x) create, or purport to create, obligations for Microsoft with respect to the Software or (y) grant, or purport to grant, to any third party any rights to or immunities under Microsoft's intellectual property or proprietary rights in the Software.

By way of example but not limitation of the foregoing, Recipient shall not distribute the Software, in whole or in part, in conjunction with any Publicly Available Software.

"Publicly Available Software" means each of (i) any software that contains, or is derived in any manner (in whole or in part) from, any software that is distributed as free software, open source software (e.g. Linux) or similar licensing or distribution models; and (ii) any software that requires as a condition of use, modification and/or distribution of such software that other software distributed with such software (A) be disclosed or distributed in source code form; (B) be licensed for the purpose of making derivative works; or (C) be redistributable at no charge. Publicly Available Software includes, without limitation, software licensed or distributed under any of the following licenses or distribution models, or licenses or distribution models similar to any of the following: (A) GNU's General Public License (GPL) or Lesser/Library GPL (LGPL), (B) The Artistic License (e.g., PERL), (C) the Mozilla Public License, (D) the Netscape Public License, (E) the Sun Community Source License (SCSL), and (F) the Sun Industry Standards License (SISL)."
