- A new open-source physics simulator “physim” was introduced; it parses XML free-body diagrams and integrates dynamics, aiming to serve as a backend for multi-domain simulations.  
- Participants proposed treating physical quantities (voltage, torque, force ranges) and protocol rules as first-class metadata in CAD, with interface constraints expressed as executable grammars (EBNF-like) so compliance, safety margins, and even “loophole” hacks can be automatically verified.  
- A lightweight compatibility-checking scheme was sketched: each interface carries constraint objects; during mating, type-matched evaluators return “ok/no-go,” supporting fuzzy thresholds and weighted priorities (preferred, important, critical).  
- Debate concluded that SKDB should offload heavy geometric solving to existing CAD kernels while supplying boundary conditions and non-geometric constraints itself; Intel’s forthcoming Larrabee and CUDA were cited as promising massively-parallel platforms for collision detection and constraint solving.  
- A 30 GB open-access archive of research papers and books was released at http://heybryan.org/books/papers/ and mirrored at http://sata.serveftp.org/~bryan/papers/; Kanzure’s recent bibliography (http://sata.serveftp.org/~bryan/papers/2009-04-06_2.bib) covers AFM cell mechanics, CFD microfluidics, and Reeb-graph shape analysis.  
- Steve Mann’s 2 mm eyetap frame design (wearcam.org/carpe/carpe.pdf) was reviewed, prompting discussion on resolution and cost trade-offs of fiber-optic bundles for DIY wearable displays.  
- Austin “fablab” progress: rooms being framed, MechMate CNC build stalled; a commercial 4×8 ft CNC router in San Antonio is operational but not donated; bootstrapping via university SLS-printed RepRap parts was floated.  
- Microfluidic spiral filters: literature supports only ~4 µL/s; scaling to 1 L/s would require ~225 m² channel area; iterative experimental validation proposed while acknowledging need for formal fluids coursework.
