Continuing How to cite a technical report for a double blind review process?, how would you proceed if your paper is acutally 53 pages long, most of it occupied by mathematical proofs, but you have to compress it into 10 pages (including all the appendices, and allowing for two additional pages for the bibliography) for an A*-level conference with a double-blind review process, a rebuttal and an explicit ban on relying on supplemental material? The time between the submission and the 2-day-long rebuttal is 2.5 months, which is then followed by a month till notification.
Here is a part of the guidelines:
Do not rely on supplementary material (your web site, your github repository, a youTube channel, a companion technical report or thesis) in the paper or in the rebuttal submitted during the clarification period. Supplementary information might result in revealing author identities.
Or would you consider not submitting to that particular conference, since it involves too much work which does not improve any of your results?
Several technical options are available, but I'm unsure about their acceptance in the community:
Use the PDF file with the main paper text as a container for the anonymized proofs as an embedded file, or
Upload the anonymized proofs to a (megaupload-like) file-storage service and provide the reader with a URL, or
Any of 1. and 2., with password-protected supplemental material, where the password is exposed with/after the rebuttal.
Are such solutions accepted by the community?
