Xenapp Server Access Control

Question regarding F5 and a Xenapp 6.5 farm. Can I use the F5 application delivery controllers to push 3rd party users to specific Xenapp servers. Reason for doing this is i need to license my organisations Xenapp servers for Microsoft 3rd party connector licensing. These licences are expensive and rather than licence the entire farm so If we can direct 3rd parties to specific servers then potentially we only need to license those with the expensive MS licences rather than the whole farm.:)
