Is it possible to send text to Replete via a URL, etc. from another app, etc for evaluation?

and you could edit text in Lisping and send it to Replete for evaluation. (The generic hooks still exist in Replete, so in theory other apps could do the same.)
When Lisping existed (it is evidently no longer available), I was never really motivated to use it to develop code with Replete.
