I e-mailed them asking if people who purchased 2 or more of the Home licenses could still use the 3.0 version of the LAN Update server that was available for the 2.7 version. I still have yet to receive a response. I contacted an Eset reseller and he confirmed it.
I have also noticed that the 3.0 Home version of the software does not mention being compatible with Windows Server 2003. Has anyone tried to use it on a Windows Server machine? One of the major reasons that I went with Nod32 three years ago was because I didn't have to pay more for a server license for a simple Home server.
I hope they don't go the way of the big guys (Symantec and McAfee) and telling the consumers what they want rather than the other way around. I am sticking with version 2.7 for the moment and hopefully Eset comes to their senses.
EDIT: Directly from the Eset web page:
Server Installation: ESET NOD32 Antivirus Business Edition may be installed on servers as well as workstations (the Home Edition can only be installed on workstations).
Home user license cost per year (with 4-pack of two years): $18.00
Business user license cost per year (with 5-pack of two years): $32.50
Sorry, didn't mean to steal the thread...
Hopefully they respond with an answer to your problem.
