No 3.0 is only for the fancy devices whose manufactures have paid Google to have it before everyone else. Once Google releases 3.0 to everyone, you might be able to upgrade it, but it's very likely that you'll have to do it manually and it will be a user porting it to that device, not the manufacturer.
Though, if it's very similar to an existing 3.0 device (very unlikely given it's low specs), you might be able to find a hacked version of that rom and cram it on.
Try to find a user forum geared towards that tablet, many have an active hacking scene.
I have heard mixed reviews of Honeycomb on tablets that weren't built for it. I would try to see if you can find a version of Cyanogenmod that will work on your device. I have Cyanogen, and it's really nice. I have been meaning to try Honeycomb (there is a hacked rom of it available for my tablet), but I haven't gotten around to it.
BTW I have a Nook Color
with Cyanogenmod7 on it. Typically the only way that you'll find a Honeycomb rom available for your device is if it has an active hacking community behind it. So I'd give the same recommendation as tom61, see if there is a forum dedicated to hacking your particular tablet.
