Just for the record: you can create a custom list/show function, which
adds the header:

"lists": {
mylist : "function(head, req) { start({\"code\": 200, \"headers\":
{\"X-Update-Seq\": (\"\"}}); send(\"whatever\"); }"

One comment: you need to convert the update_seq into a string before
sending it back via start() - might be a bug.
