ah, 'tis true it could be built on top of TK or AJAX but the low level
details are somewhat different and always painful. TK does callbacks
and needs a function whereas AJAX would need to listen for XML requests
on a socket.

and though CLIM is high level it appears to allow you to manipulate
regions in ways that may not have low level support and have to be
simulated (e.g. X-banded vs Y-banded regions).

anyway i'm still very far away from these detail as i'm taking a top-down
approach to learning the problem. if nothing else i will have successfully
merged the documentation with the source code as a literate program.

but i do think that the general purpose browser interface is worth
considering because it's becoming much more of a "platform" than
a "front-end" facade. that is, it's providing a lot of features
in a ready-built way rather than just printing text.

i was looking for an API for the browser but it looks like javascript
is the only game in town. javascript, it appears, will allow you to
redefine functions on the fly so in theory i suppose i could build
a lisp-javascript compiler-like thingie to push functions into the
browser.

it's all speculative at this point. i'll know better when the 
funcall meets the arglist.
