I suggest using virgin.media and business.virgin.media.
I would like to see Virgin Media ask ICANN to allow them to buy the vm (g)TLD and allow Virgin Media to host a website on the vm (g)TLD.
Taking the Virgin Media vm (g)TLD further:
phone.home.vm - home phone (SIP or digital copper)
sip.business.vm - business SIP
custom.business.vm - custom business solutions
custom.enterprise.vm - custom enterprise solutions
df.business.vm - dark fibre offerings
