A question about multiple boot options and live boot iso images

[Bret Busby]

Hello.

A possibility has occurred to me, and, I do not know whether it has
been done, whether it can be easily set up, with what now exists, or,
whether it is something that would need to be developed, to put it
into practice.

Recently, Ralf Mardorf posted a link in the thread about tiny kernels,
to a wikipedia comparison of "lightweight Linux distributions", that
can run with lesser resource requirements, than mainstream Linux
distributions.

So, it led me to wonder, as some distributions can be run as live
versions, where they boot from the removable optical drive (be it CD
or DVD, and, some (or all of those - I am not sure) can boot from
removable USB drives ("thumbdrives"), where a computer's BIOS permits
booting from removable USB drives, and, as provision exists, via GRUB
(and, I think, other boot managers), for a user to choose, when
booting from an internal hard drive, which operating system, be it a
choice between non-Linux OS's and a single Linux distribution and
version, or, between multiple Linux distributions and version numbers,
and, non-Linux OS's, whether something like a removable USB drive can
be easily set up, with GRUB, or, something like it, so that a user can
have multiple Linux distributions/versions live boot iso images, on
the same removable USB drive, and, upon booting into the removable USB
drive, be given the option of which distribution/(version number of a
distribution), into which, to boot, to find which, is a good match for
a particular computer's resources, so, I assume, having a GRUB, or
similar, interface, on the removable USB drive?
