[44net] seeking vps host for use as 44net hub

I'm presently looking for a virtual private server host to setup as a hub for my 44net address block. it has been mentioned when I tried this in the past that some virtualization technologies work better than others when it comes to setting up a linux virtual machine with the tunnel mesh (then subneting the netblock and routing it over various vpn links). i.e. xen hvm vs xen pvm vs kvm vs vmware.... Also does anyone know a vps provider that might bgp announce a /24 block and properly feed it to a vps on their network? Thanks, Eric AF6EP
