Can you help me with my software licensing issue?

According to the license agreement for Windows 7:

You may allow up to 20 other devices to access software installed on the licensed computer to use only File Services, Print Services, Internet Information Services and Internet Connection Sharing and Telephony Services.

Since it doesn't mentioned 3rd party TCP connections I assume that Microsoft now allows "unlimited" inbound connections?

It didn't used to: see this Microsoft article about Inbound connections on XP.

I ask because for our software can accept many TCP connections (from other instances of our software), and we don't want to break any license agreements by doing so.

This question was marked as an exact duplicate of an existing question.

Interesting how this question is closed because it contains the words license and licensing, yet the 2nd link in TheCleaner's answer, which is essentially the same question, doesn't get closed because the question avoids using the words license or licensing. – Bryan Jul 9 '12 at 16:23
We're online, we don't need to be polite! I thought the point of these communities is that they're ... well ... communal? Ring your Mums and see how they would respond to such a question. Perhaps something like "Sorry, licensing questions can't be answered because they're too complicated" – noelicus Jul 10 '12 at 8:43

This has been answered before:

Do TCP/UDP connections add to the Windows incoming connection limit?

The limit is 20 if you do a "net config server" from a cmd prompt you will see this as well.
