Update SLD's and blocks from internet

Is there any chance to use sld images from internet in a DCL file? So far I have this local configuration and it is working/reading pretty good but Ï am wondering if it would be possible to use it from another computer since I am always moving and sometimes I am working from home.

(start_image "SAMPLE")(slide_image 0 0 (dimx_tile "SAMPLE") (dimy_tile "SAMPLE") "c:/sample /sample.sld")(end_image)

I would like something like this

(start_image "SAMPLE")(slide_image 0 0 (dimx_tile "SAMPLE") (dimy_tile "SAMPLE") "http://www.sample/sample /sample.sld")(end_image)

I would like to be able to change that information in my lisp file for a place located on an external server and get it through internet. Is it possible?

AND

Is it possible to overwrite a block with another with the same name through internet?

Still having the same problem because sometimes I work from home and it would be very helpful to have the same library wherever I go. I solved the problem locally like this

(COMMAND "INSERT" "sample=C:/sample/sample.dwg" pause "1" "1" "0")

But of course this is not working

(COMMAND "INSERT" "sample=http://www.sample.com/sample/sample.dwg" pause "1" "1" "0")

Thanks
