Twonky on Thecus N2310 NAS - Manager or Server?

I am currently using the trial version of Twonky on a Thecus N2310 NAS. Assuming I find this a good solution:
1. If I buy a Twonky Manager license (instead of a Twonky Server license) will this work for my N2310 platform?
2. If a Twonky Manager license will work, does this enable me to run Twonky Manager on my Win7 Pro64 PC concurrently with Twonky on my Thecus N2310 NAS?

TIA for any help/advice!
