Would it necessarily need to be so slow?  It seems to me that edits are
pretty much prohibited during an org-goto, so could you not just build
the agenda once for the org-goto session and then filter it to the
subtree?  Could that speed it up more, or is it the filtering itself
which is slow?  I appreciate this might not be the case, or it might not
be possible to architect the system to support this.

Either way my mentioning of follow was more to indicate the interaction
style and browsable nature it encourages, rather than the instantaneous
nature of it.  Pressing a single key to rebuild the agenda view for the
current subtree would be fantastic and probably easier for you to
implement :-)

Interesting...  It seems that the org-goto idea and your sidebuffer idea
are similar.  You're right that it might not be needed, but it seems
that it might be quite nice to render user-defined subtrees in the
sidebar, as a kind of shortcut to current projects or outlines of
concern.  You're right that it might not be adding any real
functionality, but I can see that it might make navigating
easier/quicker for some users.  One potential problem is that org seems
to encourage outlines to be titles (and consequently they're quite
long).  If this were to be browseable in a sidebar you might want
represent them with aliases or shortened names, property drawers would
be an obvious way to implement this.
