There is no explicit limit in our API AFAICT, however there is a generic 
limit how big the maximum HGCM request can be, which is the mechanism 
used to exchange guest property information between the guest and host. 
Can't find the exact value for that right now, but it's in the order of 
a MByte to prevent DoS attacks.
