DMT:
	John reports that support for static structures for the new calibration
	frame file format has been started. Stuart reports that Junwei's
	DMT offline RPM has been installed on the CIT cluster and Natalia
	who has otherwise been unable to run DMT code at CIT is going to
	test it today.

LDAS:
	Ed reports progress on running under tcl-8.4.12 which is a milestone
	in getting 64-bit Solaris support (Linux appears to be in good shape
	as well). The tclglobus-1.0 release has been made and RPM's built
	and tested against LDG-4.0 are available to be added to the LSCSOFT
	repository. The workflow GUI is now partially functional.

GLUE:
	Duncan reports that GEO segments are starting to be published at CIT
	by Chris Messenger with help from Ben Johnson. Recently Keith T
	attempted and failed to get LSCdataFind running inside the CIT
	cluster. This appears to be an issue to Condor X.509 proxy delegation
	and is something that has not been tried before. Stuart suggested
	that perhaps we should have a host/IP based authentication method
	for LSCdataFind/LDRdataFindServer that would allow for local
	cluster queries without a need for certificates.

MATAPPS:
	Keith reports that nightly builds are working but the HTML updates
	for this are not yet being posted--should be up in a day or two.
	Work is ongoing to support the new LDR (0.7) convention for multiple
	IFO lists, i.e., using comma as a delimiter. There are still problems
	with using FrameL to generate burst MDC frames on the Lab clusters
	due to a ~1GB memory restriction per job. Ed Maros indicates that
	there is an option to do in memory compression which should help
	since the output files are only ~20MByte.

LAL:
	Jolien indicates nothing to report.

LDR:
	Brian indicates nothing to report.

Onasys:
	Kipp thinks everyone has upgraded to the new version and Duncan
	reports that the new automatic cleanup code needs a longer timer
	to prevent false negatives in the control room.


AOB:	Jolien is working with Brian on the new calibration frame format
	and the ad hoc committee appointed last week was encouraged to
	have their first meeting to make sure we all agree on where this
	is headed.

	Stuart reports that LDAS-CIT is now running with several software
	updates that users should help validate before the updates are
	pushed out to LHO/LLO/MIT: Condor-6.7.19, LDG-4.0, DMT-offline RPM.
