I've been reading about partition limits, MBR-style, and GPT-style partitions and I sorta like what this guy has to say: http://insan-it.blogspot.com/2010/09...ersus-lvm.html

That being said I've used LVM enough to be comfortable but I've never had an "all-LVM" volume without a partition table. First:
1) Is this possible? Can I boot off an LVM volume?
2) If not, than can I try this guy's idea and create a small (512MB) /boot partition and embed LVM into the remainder of the disk? Can you create an LVM physical volume at an arbitrary offset (in this case at the end of the partitions)? I've looked into using loopback to achieve this since losetup takes an offset but what is the size limitation on loopback devices?

LVM is a bigger kludge than all the previous partitioning schema.
Try a LVM volume (yes you can) on Windoze. End of story as far as the majority (almost all) of the world is concerned.

Grub2 supports booting from LVM.

How do you figure? It seems wisely conceived and designed.

It really doesn't matter how complex it is internally because what it does most importantly is remove the manual work for managing the details of allocating diskspace from the user/administrator.

I tried the Grub2 thing...and failed. It won't work as LVM does not allow you to reserve enough space for the bootloader:
