well, merced itself is meant to be a test bed for intels 64bit world, allowing programmers and others to produce applications which can realistically take advantage of the itanium architecture. while is for commercial use, it's not meant for enterprise usage, which is really a consumer but at the biz level. when mckinley comes out, then its supposed to be the enterprise server, super computing if you will, and intel will lure companies with applications that those users of merced have created.
i expect massive bug problems =)
