Thank you so much , J65nko , Ocicat , Jggimi !!! for your support ...
I purposefully described it as a simple desktop/worksation .. not attached to any network but a router .. I guess I'd use J56nko's

as for p2p , at times I use amule and disable the sharing option , so that nobody can see the shared files .. with this plus obfuscation support and tor+polipo .. is p2p still a security risk ?
