It would be nice, to receive answer from somebody from VMware. I saw it used comercially (for evaluation of other software and hosting small internal web servers) during my internship. Now I am close to convince boss at my present company to start using it. But not being sure about license I can do nothing.

Whatever license terms they use, the only thing they can do is not give you support if it doesn't work. Software aimed at personal use can always be bought and used by a commercial company. This is comparable not only to things like ball points or sweets you can by at your local supermarket (and use it for your company or give to customers), but also to DSL lines offered by numerous ISPs. You can use it, but don't expect VMware to fix things if you run into problems.

So, it's kind of a legal issue, in the sense that one can not give any guarantees as to fitness for a particular purpose, etc. etc. If you use VMware Server commercially, you better not give uptime guarantees to your customers if you're not willing to pay the bill if it doesn't work. So don't build your business on top of VMware Server if you want to be able to send a claim to VMware if things break down.

(On a side note, I'd expect VMware has "fitness for a particular purpose"-like clauses even for their commercial versions. So legally you might still be on your own if things break down.)

My licence, which I got after registering, is a full licence and doesn't expire so evaluation terms are irrelevant. Interestingly, I can change the number of servers licensed. up to a maximum of a mere 999, on the product and dowload page.

But I don't work for VMware ....

Apart from the non-commercial use phrase I find this one rather limiting. (all in the last few lines)

Subject to the above, each copy of the Software may not be used by any other person, whether or not such person is employed by or otherwise associated with your entity.

And this one doesn't really make sense if you can install the server on up to 10 machines

i) install or have installed a single instance of the Software and each Licensed Additional Module on a single Server, unless permitted by VMware to have multiple instances on a single Server or to have multiple instances on multiple Servers

We are looking to virtualise a small testbench of desktop PCs running windows and windows apps. A VMware server on each box seemed like a good fit.
