Hope this corpus will be distributed in the same way as clec. Most of the corpora in China are made on public funds, but the face-to-face-with-text use is only confined to a handful of compilers. Of course, their effort should be awarded, for example, by money paid for the manual, but public benefit should also be taken into consideration.
We have just developed the "College Learner Spoken English Corpus" (COLSEC), a sister corpus of the CLEC (College Learner English Corpus), and the CD-ROM of which will be published together with our book by Shanghai Foreign Languages Education Press (上海外语教育出版社) in October this year. Hope it helps. That will save you months of drugeries.
