Be aware that the limit is cited in the EULA and any workaround to increase
this limit will put you out of compliance with the EULA.
The limit is in section 1.3:
"1.3 Device Connections. You may permit a maximum of ten (10) computers
or other electronic devices (each a "Device") to connect to the Workstation
Computer to
utilize one or more of the following services of the Software: File
Services, Print Services,
Internet Information Services, Internet Connection Sharing and telephony
services. The
ten connection maximum includes any indirect connections made through
"multiplexing" or other software or hardware which pools or aggregates
connections.
This ten connection maximum does not apply to other uses of the Software,
such as
synchronizing data between a Device and the Workstation Computer, provided
only
one user uses, accesses, displays or runs the Software at any one time. This
Section 1.3
does not grant you rights to access a Workstation Computer Session from any
Device. A
"Session" means any use of the Software that enables functionality similar
to that
available to an end user who is interacting with the Workstation Computer
through any
combination of input, output and display peripherals."
